How to fight the multi-SIM users and prepaid churn phenomenons

Prepaid markets users juggle with SIM cards. These cost-conscious users accumulate SIM cards to take advantage of the best voice and data offers, even owning multiple SIM cards from a same operator (the so-called returning users). Their unused SIM cards quickly become dormant and wasted. This multi-SIM user phenomenon increases churn and the SIM card volumes operators need to distribute, as, in many prepaid markets, most SIM cards are for returning users. In addition, the development of affordable multi-SIM devices has encouraged the multi-SIM user phenomenon, particularly in Africa and Asia.
